Claims;

This invention relates to safety razors and it consists in the novelfeatures, hereinafter de scribed and claimed.

In general, the invention may apply to a com- 5 plete safety razorincluding a blade and blade holding device, but the primary object ofthe invention is to provide a blade holder and handle of simple,inexpensiveand practical design to meet all requirements and adapted tothe use of the many types of safety razor blades now on the market. Therazor blades may be slotted or cut oultdat their centers, or the saidblades may be With the above object in view, the safety razor includes abed plate provided at its ends with flanges adapted to engage the endedges of the razor blade so that the said blade cannot movelongitudinally, there being slot and lug engagement between the razorblade and the flanges to prevent relative transverse movement of theblade. The invention further contemplates the provision of a guardmember pivoted between the flanges and having teeth adapted to bearagainst the side of the blade when the guard member is swung or turnedwhereby the blade is firmly clamped in position against the bed plate,and is curved slightly so that the cutting edge of the blade will beproperly presented to the hair during the use of the razor. Handlesections are provided for swinging the guard member and for supportingthe holder, and securing devices are provided upon the handle sectionsfor temporarily fixing the same withrelation to each other to form acomplete handle, which may be used for manipulating the razor over thesurface bearing the hair.

With the foregoing objects in view, the invention is included in twoforms in one of which a plurality of guard members is used, and a dou-4o ble edged blade is employed. In the other form, a single guard memberis used and the blade is provided with but a single cutting edge.

. In the accompanying drawing:

Fig. 1 is a perspective view of one form of the safety razor wherein adouble edged blade is used and a plurality of guard members employed.

Fig. 2 is a perspective view of the safety razor showing the partsinopenposition, and the blade removed from the holder.

Fig. 3 is a longitudinal sectional view of the safety razor showing thehandle members thereof closed together.

Fig. 4 is a fragmentary'longitudinal sectional view of the safety razorshowing the handle members at open position.

Fig. 5 is a perspective view of another form of the safety razor.

Fig. 6 is a fragmentary sectional view of the form of razor as shown inFig. 5, and showing the handle members closed.

Fig. 7 is a fragmentary sectional View of the form of safety razor asshown in Fig. 5 and showing the handle members at open position.

Fig. 8 is a transverse sectional view of the safety razor cut on theline 8--8 of Fig. 7.

Fig. 9 is an end view of the handle members of the safety razor asshownin Fig. 5 and illustrating one form of security device fortemporarily connecting the handle members together.

In the form of the invention as illustrated in Figs. 1 to 4 inclusive,the safety razor comprises a bed plate 1 having upstanding flanges 2 atthe ends thereof. The flanges at one side edge of the plate are spacedfrom the flanges at the opposite side edge to provide clearance spacethru which the bristles and lather may pass during the act of shaving.

A guard member 3 is pivoted at its ends between the flanges 2 at thesame side edge of the bed plate 1 and spaced teeth 4 are carried by theguard member. These teeth have pointed ends and they are adapted toswing about the axis of the guard memberwhen the same is turned andserve as means for clamping the razor blade in position upon the bedplate as will be hereinafter explained.

Handle sections 5 are attached to the guard members 3, and securingdevices 6 are carried at the free ends of the handle sections 5 andserve to connect the said sections together to form a handle, as shownin Fig. 1 of the drawing.

A blade 7 is provided at its ends with lugs 8, which are adapted to fitbetween the flanges 2 at the opposite side edges of the guard plate. Theblade is provided with the longitudinal slot 9 that it may readily flexor bend when encountered by the teeth 4, and thus the blade is securelyheld in position upon the plate. During the act of shaving, either ofthe two longitudinal edges of the blade may be used for shaving.

In the form of the invention, as illustrated in Figs. 5 to 9 inclusive,the razor consists of a bed plate 10, provided with a shank 11. Flanges12 are struck up from the end edges of the bed v plate 10 and a guardmember 13 is pivoted between said flanges. Teeth 14 are can'ied. by theguard member 13. Handle sections 15 are provided, and one of them iscarried by the shank 11 and. the other by the guard member 13.

Securing deviceslfi are carried at the free ends no of the handlesections 15 and said securing devices are in the form of globularextensions adapted to overlap each other and frictionally engage eachother, as shown in Fig. 5 of the drawing and whereby the handle sectionsare temporarily secured together to form a handle.

The blade 1'7 is provided with but a single cutting edge and the saidblade is provided at its ends with notches 19 adapted to receive lugs 18turned inwardly from the inner ends of the flanges 12.

In both forms of the invention it will be seen that a bed plate havingflanges at its ends is provided and that a razor blade fits between saidflanges and engages the same so that relative longitudinal and lateralmovement of the blade is prevented, also a guard member is pivotedbetween the flanges and is provided with teeth adapted to engage theside of the blade and flex thesame whereby the blade is firmly clampedin position against the side of the bed plate.

Having described the invention, what is claimed 1. A safety razorcomprising a bed plate provided at its ends with upstanding flanges, ablade adapted to rest upon the bed plate between the flanges, therebeing lug and slot engagement between the blade and flanges, a guardpivoted between the flanges and teeth carried by the guard and adaptedto engage the blade and flex the same in position against the bed plate.

2. A safety razor comprising a bed plate provided at its ends withupstanding flanges, a blade fitting between the flanges, means forholding the blade against movement with relation to the flanges, guardmembers pivoted to the flanges and 4. A safety razor comprising a bedplate provided at its corners with upstanding flanges, said flanges atthe ends of the plates being spaced from each other to provide clearancespace for the exit of lather, a blade resting upon the bed plate andengaging the edges of the flanges, guard members pivoted to the flangesand having teeth adapted to engage the blade and flex the same, andhandle sections carried by the guard members.

5. A safety razor comprising a bed plate provided at its ends withflanges having inturned lug extremities, a blade adapted to rest uponthe plate and having at its ends slots adapted to receive the lugextremities of the flanges, a handle section connected with the bedplate, -a guard member pivoted between theflanges and having teethadapted to engage the side of'the blade and flex the same against thebed plate, a. handle section carried by the guard member and a.seeuringdevice for temporarily connecting the handle sections together.
